While Klopp called for more from Liverpool's leading scorer from last season, the manager was thrilled with Alisson, who recorded a second consecutive clean sheet.

The Brazil international – who acrobatically kept out Luka Milivojevic free-kick early in the second half - has quickly settled in at his new club following his arrival from Roma.

"The free-kick save was outstanding," Klopp said of Alisson's eye-catching save. "I saw it, it was not the goalkeeper’s corner, so it was quite impressive, so was the save from the [Christian] Benteke header.

"Around each set-piece, Palace block the goalkeeper and [Virgil] van Dijk, and both were most decisive in these situations. They worked through the forest of people. That was all good.

"But it was not a brilliant football game from us. We won it because we scored in two very decisive moments. That’s good, a big step for us. Everyone who watches us knows if we are not brilliant we usually lose. Today we were not brilliant but we still won. That was nice!"
